Some recent GEOTRACES science findings are reported below.
This new compilation and gridded datasets offer a concrete way forward to improve the application of neodymium isotopes as a useful tracer of ocean circulation.
Paffrath and co-autors followed the relative contributions of the main Siberian rivers to the waters of the Transpolar Drift using neodymium parameters.
Roy-Barman and co-authors established the dissolution rates from Saharan dust reaching Mediterranean seawater.
The results evidence that the effect of advection cannot be neglected in areas where a conjunction of significant horizontal dissolved aluminium gradients and significant horizontal currents is found.
One of the main consequences of this work is that manganese should be included in ocean-climate models, more particularly to improve the accuracy of their predictions in this area.
Homoky and co-workers determined the isotope composition of dissolved iron profiles in shallow surface sediments of the South Atlantic Uruguayan margin…
Oka and colleagues demonstrate that the global distribution of REE can be reproduced by considering the internal cycle associated with reversible scavenging and external REEs inputs around continental regions.
This study demonstrates the importance of biology and ecology to understanding iron biogeochemistry.
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.
